标题： (Pre-)Modern (Non-)Fermi liquids

摘要： 本注释解决了在强相互作用（非）费米液体中构建集体模式的适当玻色化描述的问题，这在二维空间中是特有的。 尽管以一种温和的形式，这种微妙之处也存在于费米液体中，但讨论集中在长程和/或延迟相互作用的影响上，这些相互作用可以完全破坏费米子准粒子。 目前的分析还进一步揭示了此类系统中集体玻色子模式的本质和特性。 显示英文摘要

摘要： This note addresses the problem of constructing a proper bosonized description of the collective modes in strongly interacting (non-)Fermi liquids which is specific to two spatial dimensions. Although, in a mild form, this subtlety exists in the Fermi liquid as well, the discussion focuses on the effects of long-ranged and/or retarded interactions which can completely destroy the fermionic quasiparticles. The present analysis also provides a further insight into the nature and properties of the collective bosonic modes in such systems.
